8.7.12
Modbus/TCP Server
To configure the Modbus/TCP server, click on the
Ethernet Configuration
tab,
check
Modbus/TCP Server
in the “Protocol” dropdown menu to enable the
driver, and then click on the
Modbus/TCP Server
subtab. By default, the
gateway’s entire database is accessible via the register mapping mechanism
discussed in section 11.12.1.2.2.
8.7.12.1
Protocol Selection Group
Timeout Time
Refer to section 8.3.1.
8.7.12.2
Connection Timeout Options Group
This group contains a selection to enable the gateway’s Modbus “supervisory
timer” function. This timer provides the ability for the gateway to monitor timeout
occurrences between successive Modbus/TCP socket connections, as opposed
to the standard timeout functionality (refer to section 8.3), which monitors timeout
occurrences only within the scope of each client socket connection. While this
feature provides an additional level of fail-safe functionality for those applications
that require it, there are several ramifications that must be understood prior to
enabling this capability. Before enabling this timer, therefore, it is suggested that
users read the ICC whitepaper titled “
A Discussion of Modbus/TCP Server-Side
Timeout Processing
”, which can be found in the documents section at
8.7.12.3
Register Remap Object
Optionally, registers can be remapped to different database addresses from their
default mapping using a register remap object. It also allows the user to map a
register that is not mapped into the database by default (any register above 2048)
to an address in the database. The register remap object can remap a range of
consecutive registers to any starting address in the database (as long as the
entire range is within the database). Up to 50 remap objects can be created.
Note that registers can be accessed as either holding registers or input registers.
The following describes the configurable fields for a register remap object. For
more information on register remap object editing options, refer to section 8.6.
Description
This field is a description of the register remap object. It is not used on the
gateway, but serves as a reference for the user. Enter a string of up to 18
characters in length.
Start Reg
This field is the starting register number for a range of registers to be remapped.
Enter a value between 1 and 65535 (0x1 – 0xFFFF).
